How it works

Derivative

Pick a fighter, choose Derivative, and trust your numbers. The faster and cleaner you solve, the harder you hit — from gentle early grades all the way to Olympic-level challenges.

A derivative measures how fast something is changing — the steepness of the curve at a point.

The power rule: d/dx of axⁿ is (a·n)·xⁿ⁻¹ — multiply by the exponent, then drop the exponent by one. So d/dx of 3x² is 6x; at x = 2 that's 12.

Apply the rule, plug in the point, and type the slope.
